    Perfect!

    This is exactly what I was looking for to complete my AR pistol build. I was hesitant about going any shorter than 9", as it will be paired with a suppressor, and I was concerned about excessive fouling from residue and powder not burning completely in such a short barrel. However, the new Hornady Black is supposed to address that issue with their quick burning powders. Great finish, easy installation, just right!

    Great barrel and Superb shipping

    I ordered on Monday, received it on Wednesday. Sorry, but it looks like I got the last one. All parts are top quality and shipped in very secure packaging. The gas block went on easily due to the barrel already being dimpled and the QPQ gas tube included the pin. So 15 minutes later and I'm already making brass. Accuracy looks great with MBUS open sights in the back yard. Will mount optics and hit the range this weekend. It's great finding a dealer in Florida instead of the Left Coast. Thanks Right to Bear Arms and Supply. I'll be back soon and highly recommend you to my friends. I just wish you had included some decals for my range gear and truck window I'm only using this cheap gas block until you email me the Superlative Arms adjustable block is back in stock.

    $60 cheaper than midwayusa.com!

    Super impressed with right to bear.com. I got the same barrel for $60 less than a large guns parts website. Shipping was extremely fast! Thanks to them im hoping to finish my 300 BLK build this week.

    Great Barrel!

    Never looked down a prettier barrel and the accuracy is outstanding. IMHO you can spend a lot more, but will not get a better barrel. Can't say enough good things about Right To Bear Arms and Supply. Great prices and fast shipping at a very fair rate.
